First the nuts and bolts: The initial price for a single share of Twitter stock will be set $26, and the company is offering 70 million shares at the open. However, the actual "opening" could be much higher, depending on what investors are actually willing to pay once trading begins. (Update: The stock opened around 10:45 a.m. at $45.10, almost 60 percent higher than offering price. It briefly surged above $60, but is currently hovering near the opening.) The stock will trade on the New York Stock Exchange under the symbol TWTR.

If those numbers hold, the company stands to raise a little over $1.8 billion from the offering, putting its overall valuation at around $18.1 billion. Underwriters could also offer 10.5 million more shares if they decided to release them, meaning that the company could raise a total of $2.1 billion.

Translation: The last Off the Grid food truck gathering will be at Fort Mason on Friday, KronnerBurger will have a pop-up burger joint at the Mill Cafe on Saturday, the Spruce restaurant will begin a new brunch service on Sunday, and more information about all of that is available on Eater’s San Francisco restaurant news page.

As for who stands to get rich off the offering? More than 80 percent of the company's stock will still be controlled by the founders, employees, and early investors. Jack Dorsey, the former CEO and now Chairman, stands to make about $610 million from his 4.3 percent stake in the company. Current CEO Dick Costolo stands to make around $200 million from his 1.4 percent stake. Check out this ChartGirl (Hilary Sargent) chart for a deeper break down of the biggest winners and losers.
